This study develops a double frontier fuzzy network data envelopment analysis (FNDEA) model for assessing the sustainable supply chains. The proposed FNDEA model evaluates the optimistic and pessimistic sustainability of supply chains. The α-cut approach is used to solve the proposed models. The main contribution of this paper is to develop a novel double frontier FNDEA model in the presence of undesirable outputs. To demonstrate the applicability of the proposed approach, the sustainable supply chains of tomato paste are assessed.

基于模糊双边界网络DEA模型的番茄酱可持续供应链评估

本研究开发了一种双前沿模糊网络数据包络分析 (FNDEA) 模型，用于评估可持续供应链。拟议的 FNDEA 模型评估了供应链的乐观和悲观可持续性。该α -cut方法用来解决提出的模型。本文的主要贡献是在存在不良输出的情况下开发了一种新的双前沿 FNDEA 模型。为了证明所提出方法的适用性，对番茄酱的可持续供应链进行了评估。
